Reflective multifoil insulation panel with honeycomb structure. Suitable for masonry walls, timber...Reflective multifoil insulation panel with honeycomb structure. Suitable for masonry walls, timber frames, roofs, and ceilings. 90mm thickness provides high thermal efficiency with added acoustic comfort. Actis Hybris is a reflecting insulation product designed for use in timber frame or masonry walls, pitched roofs, and ceilings. With a honeycomb structure of honeycomb shaped polyethylene foams attached to aluminium-coated polyethylene foils is used. A particular structure made of a large number of low emissivity cavities, insulated from dust and excessive air movement, provides high thermal performance and when combined with air cavities, the low emissivity exterior sheets give extra thermal resistance. For timber frame or masonry walls, pitched roof and ceiling applications. Dimensions: 1145mm x 1200mm x 105mm. For more information, please contact our sales team.
This guide is for builders, renovators, and DIY enthusiasts seeking high-performance insulation. The Actis Hybris 90mm panel offers excellent thermal and acoustic insulation for various applications, including walls, roofs, and ceilings. A key consideration is ensuring proper installation to achieve optimal performance and air-tightness.

FAQs
What is the U-value of the Actis Hybris 90mm panel?
The U-value depends on the overall construction method. The product's thermal resistance (R-value) contributes to the total U-value of the building element. For specific U-values, consult the manufacturer's technical data or use a U-value calculator with the full system details.
Can Actis Hybris be used in floors?
While primarily designed for walls, roofs, and ceilings, its suitability for floors depends on the specific floor construction and load-bearing requirements. Consult manufacturer guidelines or a building professional for floor applications.
What is the purpose of the honeycomb structure?
The honeycomb structure creates multiple low-emissivity cavities. These trapped air pockets, combined with the reflective foils, significantly enhance thermal insulation by reducing radiant heat transfer and convection.
Do I need a vapour barrier with this insulation?
The need for a vapour barrier depends on the specific application, climate zone, and overall construction design. Hybris itself offers some vapour-control properties, but a full assessment of the building's construction is required. Always follow local building regulations.
How much area does one panel cover?
The dimensions of this specific panel are 1145mm x 1200mm. This covers an area of 1.374 square meters per panel. The pack size will determine the total coverage per pack.
What is the difference between this 90mm panel and other Hybris thicknesses?
Thicker panels offer a higher inherent thermal resistance (R-value). The 90mm panel is a good balance of performance and thickness, suitable for many applications. Thicker variants like 105mm, 125mm, 140mm, etc., provide even greater thermal insulation but require more space.
Can Actis Hybris be installed on the exterior of a building?
Actis Hybris is designed for internal installation within the building fabric (walls, roofs, ceilings). It is not typically used as an external cladding insulation system without specific system design and approval.
Troubleshooting
Reduced thermal performance
Verify that all joints and edges are properly sealed with appropriate tape. Ensure that specified air gaps are maintained and not blocked.
Difficulty cutting panels
Use a sharp utility knife or a fine-toothed saw for clean cuts. Ensure the panel is firmly supported during cutting.
Condensation forming on reflective surfaces
Ensure correct installation practices are followed, including maintaining necessary air gaps and ensuring adequate ventilation within the building structure to prevent interstitial condensation.
Pros and Cons
Pros
Excellent thermal performance reduces heating and cooling costs.
Provides added acoustic insulation for a quieter environment.
Versatile for use in walls, roofs, and ceilings.
Lightweight and easy to handle during installation.
Reflective surface enhances thermal resistance.
Cons
Requires careful installation to maintain air-tightness and thermal bridging.
May require specific sealing tapes and techniques for optimal performance.
Not a standalone insulation solution; often used in conjunction with other materials.
Requires a minimum air gap to achieve its full reflective benefit.
Setup, Compatibility & Care Instructions
Installation:
Ensure the application surface is clean and dry.
Cut the Hybris panels to size using a sharp utility knife or fine-toothed saw.
Install the panels, ensuring they fit snugly against adjacent structures. For optimal performance, maintain specified air gaps (refer to manufacturer guidelines) on the warm side of the insulation where reflective properties are utilized.
Use appropriate jointing tapes (e.g., Actis's own sealing tapes) to seal all overlaps and seams. This is critical for achieving air-tightness.
Secure the panels using appropriate fixings, ensuring they do not compromise the insulation's integrity or the integrity of any air gaps.
Compatibility:
The Actis Hybris 90mm panel is designed for use in timber frame walls, masonry walls, pitched roofs, and ceilings.
It can be used in both new build and renovation projects.
Always consult local building regulations and manufacturer guidelines for specific application requirements.
Care:
The product is designed for long-term use within building structures and requires no ongoing maintenance once installed.
Protect the insulation from prolonged exposure to moisture during storage and installation. Ensure adequate ventilation during construction.
